The TOWER-20AM® is a ground-breaking anti-masking mirror detector that provides unparalleled alarm detection in outdoor environments due to the unique patented technologies it employs. It is the first detector to prevent false alarms caused by outdoor interferences, such as rain, snow, lightning storms, swaying bushes, and free-roaming animals, while still providing reliable detection of real threats.

The TOWER-20AM features the revolutionary Octa-Quad™ technology, which uses eight PIR sensors (compared to only one used in other outdoor detectors), with each sensor acting as a Quad detector, to accurately determine whether an alarm is justified. In addition, further increasing its reliability, TOWER-20AM also has a robust housing and patented anti-masking protection that can distinguish between masking spray, rain and sprinkler irrigation to provide exceptionally high resistance to vandalism and masking.
